serial No. 852,324.

a type-bar forming and embossing machine, having a frame comprising abed 11, which may be provided with supporting legs 12, the bed forming asupport for two uprights 13 and 1-1, herein in the form of yokes havingbearings 15 and 16, in which a driving shaft 17 is journaled. rThelatter may be driven in any appropriate manner, but herein a drivinggear 18, secured thereto, meshes with a driving pinion 19, the latterbelng secured to a shaft 20. 1f it is desired to operate the machinemanually, the shafting 20 may be provided with a crank 21.

The strip of sheet steel or other Vappropriate material 22, from whichthe. type bars are to be formed, is herein supplied to the machine inthe form of a roll placed in a reel 23, herein comprising a pair of sideplates 21,1nounted to turn upon a spindle or shaft v rThis reel may beotherwise appropriately mounted, but herein its spindle or shaft ismounted .in a pair of supporting arms 26, and the latter are pivoted at27 upon the frame, in order 'that the reel with its roll of material maybe caused to act as its own brake, to prevent too rapid rotation, theroll of material for this purpose resting directly upon a guide 28 forthe strip.

As a means for guiding the strip and holding the same against lateraldisplacement, the guide 28- (see Fig. 2) is provided with a groove orchannel 29, whose width corresponds exactly wit-h that of the strip, alowing a` slight clearance to permit the same to slide freely.

rThe strip of material may be fed by any a other appropriate means, butherein I have provided feed mechanism comprising a feed slide 30,mounted to reciprocate in appropriate guidewaysl 31. rlhis' feed slideherein carries a strip-engaging member, herein in the form of a feedpawl 32. This feed pawl might engage the strip in some other appropriatemanner, to impart an intermittent feed movement thereto, but herein the.

whose rear face or edge is inclined forwardly somewhat, as shown in Fig.1, whereby it will be` readily' withdrawn simply by this rearwardmotion. The pawl may be held in engagement with the strip by gravityalone if desired, but I prefer to employ a spring 35, to assist gravity1n maintaining such engagement. The feed slide 30 herein receives itsreciprocatory moven'ient from a cam 36, to which it is connected by alink 3T and lever 38, the latter carrying a cam roll 39, engaging thecam, which preferably has a closed cam path or groove 40. The lever 38is herein'fulcrumed at 41 on a bracket 42, supported 0n the bed 1l. lThestroke which the cam mechanism imparts to the feed slide is equal to, orslightly greater than the distance Lbetween two adjacent perforations ofthe strip, so that at each for vard stroke, the latter is fed forward adistance equal to the space between two perforations.

As a means for avoiding accident to the feed mechanism, in the event ofaccidental stoppage of the feed strip by some obstruction or accident, Ihave herein provided a cam mechanism with a safety device comprising aspring 43, carried by the cam lever 3S, and engaging a pin 44, carriedby the link 3T, the strength of the spring and the arrangement of theparts being such that, in the normal operation of the machine, thespring is unyielding. and the full working stroke is imparted to thefeed slide. If, however, there should be any abnormal resistance to thefeeding movement of the strip, the spring' will yield and allow theslide to stop. while the cam lever continuesr its forward movement. Thespring 43 may be. of any other appropriate form, and otherwise mountedupon the cam lever, but herein is fixedly secured at one end to thelever by a screw 45. and is provided with means of adjustment consistingof a screw 4G. passing through the spring and threaded into the lever.whereby the free end of the spring may be caused to bear with a greateror less degree of pressure against the pin 44.

I will now describe the character-applying, impressing, stamping orembossing mechanism` by means of which the printing characters areraised or embossed, or otherwise applied to or impressed upon the strip,by the use of coperating pairs of` dies, which are so arranged that anypredetermined character or group of characters may be brought at will toan operating point in alinement with the strip, and simultaneouslycaused to impress such character. or

group of characters, thereon.

The character stamping or embosslng mechanlsm may be of otherappropriate construction, but herein comprises a guide block 47, havingaguideway for the strip, consisting of a. groove 48 (see Fig. 4), whoseside walls are spaced apart sufficiently to guide the strip and providea working clearance to allow the same to be moved freely in alongitudinal direction. The block 4T is herein provided with a recess49, extending lengthwise of the same (see Figs. 4 and' 5), to receive aseries of bars 50, slidably mounted therein and provided respectivelywith recesses 5l, containing bars 52, respectively, interengaging withthe bars 5() in such a manner as to be, movable longitudinally in unisontherewith, and yet capable of relative vertical movement (see Fig. 4).To this end, each bar 52 ismade the same length as its respective recess51, with a proper working clearance, so as to be capable of movingfreely in the vertical direct-ion, but held against lengthwise movementwith respect to the bar 50 by which it is carried. y

rIhe bars 50 may be, and preferably are, provided with handles 53, whichmay be grasped to facilitate the longitudinal shifting of the bars, andthese handles are preferably spread apart at their upper ends (see ig.'5), to enable eachpart to be readily grasped without interfering withthe others. `Each pair of bars 50 and 52 constitutes the members of apair of dies for embossing the raised characters upon the strip ofmaterial to form printing characters. If the characters are to benumerals, each pair of dies will be provided with mating numerals l to9, inclusive, and 0, and correspondingly, if letters of the alphabet areto be embossed, the coperating die members will be provided with matingletters. In the specific instance shown, four of the tive pairs of dieswill be provided with numerals and the remaining one with letters, inorder that a type bar may be formed with any desired letter of thealphabet, associated with any numeral or group of numerals up to andincluding a fourgure number. The number of pairs of dies may,`of course,be increased without departing from the .spirit or scope of theinvention. Herein, the upper dies 52 are provided with raised characters54, andthe dies 50 with depressed characters 55, as shown in'aconventional manner in Fig. 10, although it will be evident that thedies may be reversed if desired. l

As a means for holding the dies normally in spaced relation, so that thestrip may 'be fed between them without interference, any appropriatemeans may be utilized for lifting the upper set of dies, but hereineac-h I caused to coperate to press or emboss in 1'30 68, constitutingguides `in the form of tongues 69, formed Leaders the strip of materialany predetermined they will rise by permitting the stiip to be` fed.

As a means for holding the various pairs of dies in the selectedposition of adjustment, each bar l50 is herein provided with a series ofnotches 57, cooperating with a spring 58, which serves as a detentnormally holding the slide against lengthwise movement, but permittingsuch movement upon application of a suliicient amount of force'to causethe spring to be forced out of the notch in which it is located. Thespacing of the notches will, of course, correspond and be equal to thespacing between the characters upon the dies, there being one notch foreach character or pair of characters, so that any selected character orpair of characters may be brought to the working point, and held thereduring the embossing operation. The springs 58 may be of any otherappropriate type, but herein all o them are formed of a single plate(see `Fig. 6), having a raised portion 59 provided with a series ofslots 60, dividing the saine into separate resilient portions, in effecta Separate spring, but having their ends united by flanges 61-61. Thesprings may be otherwise appropriately mounted in theblock 48, butherein the latter is provided with a recess 62, in which the spring isheld by an inserted block 63. As a means for indicating to the characteror group of characters at the embossing point at any instant, l haveherein provided an indicator comprising a plate 64, having therein asight aperture 65, through which lthe operator may view a character orgroup of characters impressedupoii the bars 50 (see Fig. 5) ,thearrangement of these characters corresponding exactly with thecharacters on the embossing dies already described. Thus, if thecharacter A alone appears at the aperture, the operator is apprised thatthe impression taken Aat that moment will cause the letter A to beimpressed upon the strip;

Any other appropriate impression mechanism may be utilized, but hereinan impression slide 66, having an inserted hardened block 67 is arrangedto depress all of the bars 52 simultaneously, to cause the dies toimpress or einboss upon the strip of sheet materialv at will apredetermined group of printing characters. The impression slide 66 isherein provided with a pair of grooves guideways for a pair yof on orappropriately secured to housings 70, the latter being attached to thesides of the yokes 1 3 and 111 (see Figs. 1 and 4).,

rlhe impression slide 66-may be reciprocated vertically by anyappropriate means,

tuting a guideway, each constituting the operator` but herein isconnected by an eccentric rod and strap 71 to an eccentric 72, thelatter being secured to the driving shaft 17. The eccentric rod may beprovided with means of adjustment, herein comprising a rightandleft-threaded screw 73, provided with lock-nuts 74 and 75. By thismeans, the eccentric iod may be lengthened or shortened at will, therebyto vary the strength of the impression.

As a means for severing'the strip of material at intervals, l may employany suitable cutting mechanism as, for example, that which isillustrated, and which comprises upper and lower cutters 76 and 77, thelatter being preferably provided with an inclined face 78, the purposeof which will presently appear. The upper cutter 76 is herein securedtoa cutter slide 79, provided with a recess 80, which receives thecutter, the latter being secured to the slide 4by one or more screws 81.As a means for preventing the upper lcutter slide from lifting the stripafter a piece has been severed therefrom, l have herein provided a guideblock 82, having a groove 83 constiin which the strip of material isheld by overlying plates 84 (see Fig. 3), herein secured to the guideblock by screws 85. y

rlhe cutter' slide may be reciprocated vertically by any suitablemechanism, such for example as an eccentric rod and strap 86, and aneccentric 87, the latter being-secured to the driving shaft 17. Theeccentric rod may, if desired, be provided with means of adjustment,herein comprising a rightand left-threaded screw 88 having lock-nuts 89,by means of which the cutter slide may be adjusted, so that the uppercutter will properly coperate with the ,lower cutter. The `eccentric 87is set so 'that the cutter slide is properly timed to cause the strip tobe severed contemporaneously with the embossing operation, and bothoccur in the interval between the feeding operations.

After the strip has been embossed and severed, as already described, thesevered piece is next formed with two lateral flanges projecting in adirection opposite to that of the raised characters,vand the completedtype bar is then ejected from 'the machine. rlliis may be accomplishedby other appropriate means, but herein the piece, after being severedfrom the strip, is advanced slightly by the action of the inclinedsurface 7 8, already referred to, until the forward end of the piecestrikes an abutment 90, which limits its forward movement, 'and it thendrops upon two ledges 91, which support it in readiness for the nextoperation. rl`hese ledges, it will be observed by reference to' Fig. 7,are separated by a space 92, which corresponds to the width thecompleted type bar is to have. These ledges are appropriately formed on,or secured to, a pair of, guide lugs 93, separated by a space 91 veryslightly greater than the Width of the severed piece of the strip, sothat the same is accurately held against lateral displacement. A formingblock, or plunger, 95 non7 descends upon the piece, and forces the samethrough the opening 92, the thickness of the block or plunger beingapproximately equal to the Width of the space 92 minus twice thethickness of the strip, so that as the block passes through the openingand forces the piece therethrough, right-angle flanges 96 are formed,and a completed type bar 97 is ejected through the bottom of an outletopening 98.

The plunger or forming block 95 may be actuated by any suitablemechanism, as for example a vertically reciprocating slide 99, y

operated by an eccentric rod and strap 100 and eccentric 101. Theeccentric rod may be provided With means of adjustment, hereincomprising a right and left-threaded screw 102, (see F ig. 1).

rllhe operation of thev forming block is preferablyv so timed that itstrikes the piece the instant after it has been severed, so that theoperation of forming, cutting and ejecting the piece take place in quicksuccession, and in fact constitute one continuous operation. It Will nowbe apparent that one completed type bar is formed with each twosucceeding impressions of the ma china-that is to say, While one set ofcharacters is being impressed upon the strip at one point, a previouslyembossed portion is being severed, formed and ejected.

1t will be observed that the article produced in this particularinstance is a type bar provided With longitudinal flanges and aperforation, and having one or more raised reversed printing characters.1t. will be remembered that the perforations, or their equivalent, Wereformed in the strip previous to theintroduction of the latter into themachine. There is a particular coaction between the feeding device andthe particular form of stock used.

lilach completed type bar isV provided with a perforation, which may beutilized to receive a pin or similar opposing element, for

the purpose of' longitudinally positioning and securing the type bar,While the longi! tudinal anges may be utilized in the transversepositioning of the type -bar in the printing machine in which the typebar is intended subsequently to be employed. The flanges also possessthe advantage of providing a reinforcement giving rigidity to the typebar, and preventing injury thereto because of distortion. j

While l have herein shown and described one specific embodiment of myinvention for illustrative purposes, and have disclosed provided Withcheck nuts 103 and discussed in detail the construction and arrangementincidental to one specific appli cation thereof, it is to be understoodthat the invention is limited neither to the mere details or relativearrangement of' parts, nor to its specific embodiment herein shown. butthat extensive deviations may be made from the illustrated form orembodiment of the invention, Without departing from the principlesthereof.
